A second thumbs-up on BotaBox. I drink its cabernet sauvignon and honestly can't taste the difference from ordinary bottled red, although I've never trained my palate in any serious way.

Because of the plastic bladder and preservation from oxidization, the BotaBox wine tastes the same from the first glass until the box is drained, normally a week, at room temperature. I imagine though that one would get that same benefit from boxes of swill like Franzia.
